cry of the type in which the rings carrying the travelers are so formed and mounted that they rotate and are driven to rotate in the same direction as the spindles with which they cooperate. The spindles are rotated in the usual manner and the rovings or other yarns or threads are delivered to them in the usual way. Vertical reciprocable motion is given to the spindles according to this invention in the manner and by the means hereinafter described for the purpose of effecting the proper winding and building up of the cop, the ring rail remaining stationary. Or the same method of and means for vertically reciprocating the ring rail may be adopted, the spindles only being rotated. Such a method of reciprocating the ring rail is intended to be included as an alternative by a description ofthe reciprocation of the spindles.

The accompanying drawings illustrate somewhat diagrammatically the arrangement of a single spindle, ring and traveler, for spinning and winding on the bare spindle and the application thereto of our improved devices for effecting the vertical reciprocation of the spindle, from which the operation of a number of rings and spindles placed in a row in the usual manner of a ring frame will be understood. The spindle is arranged to reciprocate vertically while the ring rail is stationary.

Figure 1 is a front view of the machine. Fig. 2 is a plan View of the cams employed. Fig. 3 is a view to a larger scale showing the ring in section, Fig. 4 is a view of a detail of the spindle driving device. Fig. 5 is a face view of one of the cams. Fig. 6 shows different views of another of the cams. Fig. 7 shows the cams in end view. Figs. 8 and 9 illustrate a ratchet device for actuating certain of the cams.

Referring to Fig. 1, A indicates the usual front rollers which deliver the attenuated roving to the traveler B which can be of any usual construction. This traveler engages with the top flange of the ring 0, and

this ring is driven around or rotated in the same direction as the spindle D to which it is delivering yarn. In the example illustrated the ring C is rotated by being attached to the upper face of a wherve E which is properly mounted in bearings to rotate in the ring rail F. The wherve and ring are driven by a cord G from a suitable tin roller.

The lower end of the spindle D is carried in a bearing on the vertically reciprocable frame H in such a manner that although the spindle is free to rotate it must move up and down with suchframe. This up and down movement of the spindle within its ring is the equivalent of the motion that is usually given to the ring rail and it has the same object, to properly wind the yarn on the spindle. The cam for giving this movement is indicated at J and it gives the reciprocating vertical movement to the spindle oarrying frame H through the medium of the stirrup H which surrounds the cam and engages with its-lower surface through the intermediary of a movable ball H K K are weights to slightly overbalance the weight of the frame H.

The cam J makes one revolution for a winding layer and a return binding layer of yarn upon the spindle. It is shaped to give the proper varying traverses to the spindle during the building of the cop bottom and the winding of the cop, and is preferably shaped to give a rapid upward movement to the spindle and a slower downward movement, so that the binding convolutions of yarn are laid in the known manner on the cop from the nose to the base of the conical surcop is effected by lneans of the face cam L secured to a shaft L to which one complete rotation is given during the completion of a cop. The cop bottom is built while the spindle frame H is reciprccated by the conical part of the cam shown at its left hand end; the remainder of the cam reciprocates the spindle during the winding of the remainder of the cop. A long cam J may be used which is moved axially at a constant speed during the building of the cop bottom and the winding of the cop, but it is preferred to use a short cam and to give it varying speeds of axial traverse by giving asuitable contour to the face of the cam L.

L is an arm for transmitting the motion of the cam L to the cam J. It is secured to and rocks with a vertical. rock shaft L which also has a short arm L carrying a friction bowl engaging with the cam L.

U a sliding support for the arm L The end of the arm L is connected to the shaft L by being hinged to a collar which rotates with the shaft but can slide along it.

In addition to constantly rotating, the shaft J of the cam J is progressively lowered during the formation of a cop, being at its highest position at the commencement of the building of a cop bottom and at its lowest when the cop is finished. The spindle frame, through its engagement with the cam J, and consequently the spindles are thus gradually and correspondingly lowered during the building of a cop. This is effected by mounting the shaft J in bearings which can slide up and down in brackets J (in which the frame H also slides). The shaft J is engaged by the front forked ends of two armed levers M, M, fulcrumed on a shaft M The rear ends of these levers engage by friction bowls with cams N. They and the cams ars so disposed that at the commencement of the building of a cop bottom thebowls are at the greatest diameters 1 of the cam surfaces. (See Fig. 5.) The cam shaft J is then in its highest position. The cams N rotate only once during the complete winding of a cop so that when the cop is complete the cam shaft J is in its lowest position. The shaft carrying the cams N has a step by step angular motion given to it by a pawl and ratchet or the like, one step for each complete winding and binding traverse of the spindle. This ratchet device is shown in Figs. 8 and 9. The ratchet wheel S is keyed to the shaft L" on which is loosely mounted the bell crank lever T the upright arm of which carries the pawl U engaging with the teeth of the ratchet wheel and the horizontal arm of which rests upon a cam V keyed to the shaft W driven at a suitable speed and advancing the shaft L one step for each revolution of the cam V.

Details of an intermediate bearing support for the spindle are shown in Fig. 4:. F ixed on to a suitable rail P is a bearing Q in which the spindleproperly rotates, and in which it can have longitudinal movement. Inclosed within the bearing is the wherve R, which engages by a feather key and key way or the like or by balanced keys and key ways with the spindle D. The spindle is thus compelled to rotate with the wherve R but can freely slide up and down within it. The wherve R is driven in the usual way from a tin roller.

The rotating ring C rotates at a regular speed during the operation of the machine, and its speed may have any desired relation to the speed of rotation of the spindle. As an example with a spindle rotation of 7000 a minute a ring rotation of 6000 may be employed.

As has before been explained the spindles may only rotate, as is usual in ring frames, and the vertical reciprocating motion may be given to the rotating rings. This may be effected by mounting the rings in proper rotary bearings in a ring rail, the rings being provided with downwardly extending sleeves which key for rotation with but can slide within wherves attached to and rotating on a fixed rail. The ring rail is then reciprocated in the usual manner of the present ring rails.

hen the cop is completed and dotted the different parts are returned to their commencing positions as is usual in ring spinning machinery.
